Robust is an Android hotfix framework and runtime application updater designed for patching bugs in production environments. It functions as a bytecode patcher and dynamic code injection tool, allowing for the modification of application logic without requiring a full app update or device reboot. The project enables the remediation of Android defects by injecting new classes and methods into existing builds and modifying the implementations of existing methods. It utilizes a toolchain to generate binary patch files that update application behavior and introduce workarounds on the fly. The sy

Walle is a tooling system for automating the injection of distribution channel identifiers and metadata into signed Android application binaries. It functions as a command-line utility and build pipeline extension that reads and writes custom metadata directly into the Android application signing block. The tool specifically modifies the Android Signature V2 block to embed channel identifiers and key-value pairs without re-signing the binary. This approach enables the generation of multiple channel-specific application packages without requiring a full binary rebuild or repeated signing opera

Proxyman is a cross-platform HTTP debugging proxy that captures, inspects, and modifies HTTP, HTTPS, and WebSocket traffic. It functions as a man-in-the-middle proxy, decrypting SSL/TLS traffic to allow real-time inspection and modification of encrypted requests and responses. The tool is designed for debugging web and mobile applications, with capabilities for API mocking and simulation, scriptable traffic modification, and team collaboration on network logs. What distinguishes Proxyman is its deep integration with mobile and cross-platform development workflows. It provides automated certif

Tinker is an Android hotfix framework designed to update application code, resources, and native libraries at runtime without requiring a full reinstallation or store update. It provides a comprehensive engine for injecting runtime fixes and managing the software lifecycle of deployed mobile applications. The framework distinguishes itself through a robust binary patching system that generates compact difference files between application versions, significantly reducing bandwidth usage during distribution. To ensure operational stability, it incorporates a crash-resilient safe mode that autom

an android library for debugging what we care about directly in app.
